Shower issues

[borcy]

The shower works fine pressure wise, but it's developed a problem where it starts hot and then gets cooler and cooler. So after about 3-4 minutes of being on it's luke warm.

It's got a shower pump, I think it's been in for around 2 years.

I don't know if it's the pump or something in the shower bar/controller?

My money normally would be on the shower thermostat (bar controller) however the pump you've linked to has a crossover (in the event of only one side actually pumping) so I'd check the filters on the inlet side of the pump first.

Well took the temp control end apart and cleaned it. Popped it back together but there's no flow, I'm guessing I've probably put it back together incorrectly.

I thought the flow was controlled from the other end?
